Great question...I would strongly suggest narrowing down what you want to do in the computer field. I work for a large computer company in Texas and there are 100s of different careers...sales, technical, engineering, networking, support, etc.
Below is a good link I found for you that reviews the top ten computer careers, what the jobs are like, salary and more.
Please write me back if you have questions or I can help you more...good luck! :)
